usual ; on the inner side inside the black line is a narrow 

 pinkish-ochreous stripe, its lower end curved and broadened, 

 and joining a large black patch; a thin greyish-ochreous 

 middle line edged with black across the wing, with a small 

 outward angle at its middle ; a blackish suffusion on the 

 lower disk ; a subapical white rather large spot and four discal 

 white spots in an irregular row, outwardly edged with black: 

 hind wing with the base dark brown ; an antemedial brown 

 line with a pale outer edging ; a medial somewhat crenulate 

 greyish-ochreous line in continuation of the middle line of 

 the fore wing; a subapical white spot; a discal indistinct 

 greyish-ochreous line, more or less lunular, the hollows of the 

 lunules filled in Avith black, the row deeply curved above its 

 middle and then deeply and bluntly outwardly angled below 

 its middle; body concolorous with the wings ; the first two 

 segments of the abdomen black, the third pale grey. Under- 

 side ochreous brown, the outer half dark, limited by a brownish 

 thin band across both wings ; the discal markings disposed 

 as on the upperside, the white spots larger. 



¥ . Brown with a lilac tinge ; abdomen with the first two 

 segments black ; wings of a uniform colour, the upper dark 

 portion of the male only slightly indicated except towards 

 the apex, which is dark; the whorl-shaped discoidal mark as 

 in the male ; a broad white band across both wings, broadest 

 on the hind wing, its outer side with points like a fringe; the 

 discal markings as in the male. Underside pale ochreous 

 brown ; the medial white band macular on the fore wing, 

 broad on the hind wing; the discal markings as on the 

 upperside. 



Expanse of wings, <£ 4, ? 4-fV inches. 



Hab. Cape Engano, Luzon, Philippines. 



Genus Patula, Guen. 



Patula does not possess the two curious chitiuous plates in 

 the connection between the 8th and 9th abdominal segments 

 found in Argiva; PL XI. figs. 24, 25, 26, & 27 show the 

 genitalia of the true P. macrops, drawn on the same plane as 

 in the figure of the genitalia of Argiva. In the development 

 of the coremata it agrees with Argiva ; the structure of the 

 valve and the shape of the penis are the chief points. The 

 bind wing of the male has the costal half aborted, forming 

 a fold turned over on the upper surface, containing a large 

 glandular patch of flocculent hair ; vein 4 runs to the 

 functional apex, 5 from the middle of discocellulars, 6 to 

 the fold, 7 and 8 very minute to near base of centre.
